however, cassiterite does not react with sodium hydroxide, so cassiterite is retained in tungsten residues. Centrifugal concentrator is a high effective gravity equipment to recover micro-sized (less than37um) high-density minerals (Barry et al.,2006). This study exploits a new route, centrifugal gravity separation
